Title:
  Can not upgrade to 14.04.01 LTS keeps throwing up error see below

Status in update-manager package in Ubuntu:
  New

Bug description:
  update-manager Ubuntu 14.04.01 LTS

  
  Could not determine the upgrade

  An unresolvable problem occurred while calculating the upgrade.

   This can be caused by:
   * Upgrading to a pre-release version of Ubuntu
   * Running the current pre-release version of Ubuntu
   * Unofficial software packages not provided by Ubuntu

  If none of this applies, then please report this bug using the command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal.
